Sonnax heavy duty intermediate shaft 22171B-HD is a direct replacement upgrade for Chrysler 47RE, 47RH and 48RE transmissions. OE shaft failure is common as power levels are increased and in long-distance towing applications. The Sonnax shaft is specially heat-treated and processed for maximum strength and resistance to fracture, making it the ideal upgrade for most high-horsepower street, competition or towing applications.

This shaft features many unique refinements available only from Sonnax, including a torsional design that allows energy to be absorbed, reducing peak loads to critical areas.

For the ultimate protection against breakage in competition applications, Sonnax extreme duty intermediate shaft 22171B-08K is recommended.

  • Patented modifications to lubrication channel increase lube flow to prevent gear train meltdown
